A cooking device having a sounding buzzer is known.

[0003]

In the conventional cooking apparatus described above, the notification buzzer sounds only once at the first time when the detected temperature reaches the set temperature after starting the combustion amount control based on the temperature. This is because when the detected temperature reaches the set temperature, the notification buzzer always sounds, for example,
In the case of cooking tempura, etc., the buzzer sounds when the detected temperature returns to the set temperature after the temperature of the tempura oil falls slightly below the set temperature after the object to be cooked is put into the cooking container and the buzzer sounds. This is because it frequently occurs, confusion occurs, and usability deteriorates. In addition, in the case where tempura oil is added, cooking is interrupted and the temperature of the tempura oil is raised to the set temperature. However, in the above-described conventional cooking device, even in this case,
Since the buzzer does not sound, it is not possible to judge whether the temperature has returned to the set temperature or not, and it is not easy to know when to start cooking. SUMMARY OF THE INVENTION An object of the present invention is to provide a cooking apparatus which has a notifying means for notifying when a detected temperature has reached a set temperature suitable for cooking, thereby improving usability.

[0004]

In a cooking device having a notifying means for temporarily notifying when the temperature is increased, after the notifying by the notifying means , the addition of the object to be cooked or the like is performed.
By the detected temperature is greatly reduced, when the temperature difference between the set temperature and the detected temperature exceeds a predetermined value, the informing means when the detected temperature is raised to the set temperature again again Provides a temporary notification.

[0005]

The combustion controller controls the temperature so that the temperature detected by the temperature sensor arranged in contact with the cooking container containing the object to be cooked becomes the temperature suitable for cooking set by the temperature setting means.
Control the heating power of the heating source. Notification means performs a temporary notification when the detected temperature is raised to a set temperature, after the notification, the detected temperature with additional charged etc. the food is greatly reduced, the temperature difference between the set temperature and the detected temperature When the detected temperature becomes equal to or higher than the predetermined value, the notification is temporarily performed again when the detected temperature rises to the set temperature again.

[0006]

When the detected temperature reaches a set temperature suitable for cooking, a temporary notification is made. After this notification, a small amount of food is added and the temperature difference between the detected temperature and the set temperature is determined. If it is less than the value, no notification is made even if the detected temperature reaches the set temperature again, so that the notification does not occur frequently and does not cause confusion to the user. In addition, when the detected temperature reaches a set temperature suitable for cooking, a notification is temporarily made, and after this notification, a large amount of items to be cooked is added, and the temperature difference between the detected temperature and the set temperature is equal to or more than a predetermined value. In some cases, a notification is made temporarily when the detected temperature reaches the set temperature again, so that the user can know when the detected temperature has returned to the set temperature, so that the user can cook with peace of mind and use it easily.
